1. PRODUCT OVERVIEW

This document provides the information required for the installation, operation, and verification of the GeminiG3™ wireless radio modem.

This document is designed for use by engineering design, installation, and maintenance personnel.

1.1 GENERAL DESCRIPTION

Available in 700 MHz, 800 MHz, or UHF and in 700-800 MHz Agile Dual-Band (ADB) model, GeminiG3 is a mobile radiomodem aimed at the public safety and public utility markets. It integrates all the necessary hardware for data-only vehicular installations up to but not including the laptop PC and its application software.

Examples of applications are:

1. Database inquiry systems.

Small number of brief messages, (usually from the mobile station) with fairly long responses.

2. Computer-aided dispatch (CAD).

Large number of messages, (usually from the base station) with very brief responses.

3. Autonomous Automatic Vehicle Location (AAVL).

Using built-in GPS receiver, determines position, speed and direction of fleet members.

The GeminiG3 radiomodem is made-up of:

• A main transceiver

• An auxiliary receiver for Parallel Decode™

• A 10 to 25-Watt adjustable power amplifier (700 MHz), 10 to 35 (800 MHz), 10 to 40 (UHF), 12.5 to 25 (UHF-

ACMA)

• A Gemini Processor/Modem board with DSP modem

• An integrated OEM 12-channel GPS receiver.

1.1.1 FEATURES

• ADB model allows 700/800 MHz automatic band and bandwidth switching capability during roaming.

• Parallel Decode™ (PD) technology featuring dual receivers for added decode sensitivity in multi-path and

fading environments.

• Native IP mobile model having “Stateless Data Compression” and “Protocol Reduction”, that works with

TCP/IP and UDP, uses standard 10/100 BaseT Ethernet RJ-45, and automatic MDIX to get the most efficient use of user available bandwidth without requiring a dedicated server or gateway. It acts as a router, interfaces with any Ethernet device or Native TCP/IP application, and has two RS-232 ports that can be

configured as terminal servers. Using an in-car hub or switch makes adding other peripherals, such as a

Channel Type

UHF-

Modula-

camera, possible.

• Sophisticated DSP-based modem design provides added system performance, fewer retries and more ef-

fective throughput.

• On-air data speeds and modulation types supported (dependent on “Feature Key” selected

ditionally, for ease of maintenance or upgrades, all unit firmware can be re-programmed over-the-air.

• Diagnostics combined with the optional SNMP-based Network Management System (NMS) package, gives

network administrators a proactive tool to collect and analyze diagnostic information.

Method used to implement customer’s option(s) selected at the time of radiomodem purchase (factory-installation) or as add-

on (field-installation).

1.1.2 CONFIGURATION

The GeminiG3 product is factory-configured based on each customer network system requirements and finalized by CalAmp system engineering. Network-specific operating instructions should be prepared by the system administrators in conjunction with CalAmp system engineering. Instructions and examples given in this manual are based on GeminiG3 operating software version 2.2x and may not apply to later software versions.

2. INSTALLATION

2.1 PLANNING THE INSTALLATION

2.1.1 OVERVIEW

To ensure trouble-free, efficient installation, start by inspecting the vehicle to determine the optimum position for GeminiG3 unit and its antennas as well as the routing of all associated cabling and wiring.

2.1.2 LOCATION

Often, installations in cars are done in the trunk, underneath the back window ledge or on the trunk floor. In vans and small trucks, it is usually done in the back of the vehicle. In large vehicles, it is often done in the front cabin.

Be sure to place the GeminiG3

• The LEDs can be seen (as an aid in troubleshooting)

• Access to the antenna connectors is possible without removing the unit

• Sufficient air may flow around the unit to provide adequate cooling

unit in such a way that:

The GeminiG3 unit is not fully waterproof, therefore it should be mounted sufficiently away from an opened trunk lid or opened tailgate, windows or doors to avoid exposure to rain and/or snow. It also minimizes the chance that material can be accidentally thrown on the unit or of someone bumping against it.

2.1.3 CABLE PATH

Try to route the cables away from locations where they would be exposed to heat (exhaust pipes, mufflers, tailpipes, etc.), battery acid, sharp edges, mechanical damage or where they would be a nuisance to automobile mechanics, the driver or the passengers.

Keep wiring away from automotive computer modules, other electronic modules and ignition circuits to help prevent interference between these components and radio equipment.

Try using existing holes in firewall and trunk wall and the channels above and below or beneath the doors, channels through doors and window columns that are convenient to run cables and wires.

Whenever possible, install conduit in which to run the cables.

2.2 WARNINGS

Before starting installation, review all of the following warnings.

2.2.1 RF RADIATION WARNING

Recommended safety guidelines for the human exposure to radio frequency electromagnetic energy are contained in the Canadian Safety Code 6 and the Federal Communications Commission (FCC) Bulletin 65. Proper installation of the transceiver antenna of GeminiG3 radiomodem as summarized in section 2.5 will result in user exposure substantially below the recommended limits for the general public.

Qualified personnel must do all antenna installations. See paragraph 2.5.2 for recommended antenna positioning.

Transmissions when persons or animals outside the vehicle are within two feet of the antenna may result in radio energy radiation burns or related injuries.

2.2.2 INTERFERENCE WITH VEHICULAR ELECTRONICS

Certain vehicle electronic devices may be prone to malfunction due to lack of protection from radio frequency energy present when transmitting.

It includes, and is not limited to:

• Electronic fuel injection systems

• Electronic anti-skid braking systems

• Electronic cruise control systems

If the installation vehicle contains such equipment, consult the dealer for the make of vehicle and enlist his aid in determining if such electronic circuits will perform normally when the radio is transmitting.

2.2.3 SECURE MOUNTING

For vehicle occupant(s) safety, mount the GeminiG3 radiomodem securely so that the unit will not break loose in case of an accident or violent maneuvers.

2.2.4 EXPLOSIVE ENVIRONMENTS

Operation of vehicular radio transmitters in explosive environments may be hazardous and conventional safety precautions must prevail. These include and are not limited to:

• Transmitting while fuelling the vehicle. Do not carry fuel containers in the same compartment as the

GeminiG3 unit.

• Dynamite blasting caps may explode when transmitting radio operation takes place within 500 feet.

Always obey the “Turn Off Two-Way Radios” signs posted at sites where dynamite is being used.

If transporting blasting caps, (check applicable local bylaws) be aware to:

a) Carry the blasting caps in an appropriate metal container having a soft cushioning lining.

b) Suppress transmissions whenever the blasting caps container is being loaded or unloaded into or

from the vehicle.

2.2.5 INSTALLATION IN VEHICLES POWERED BY LIQUEFIED GAS.

GeminiG3 radiomodem installations in vehicles powered by liquefied petroleum gas with the LP-gas container in the trunk or other sealed-off space within the interior of the vehicle must conform to the National Fire Protection Association Standard NFPA 58 which requires:

• Space containing radio equipment shall be isolated by a seal from the space containing the LP-gas

container and its fittings.

• Outside filling connections shall be used for the LP-gas container.

The LP-gas container space shall be vented to the outside of the vehicle.

2.3 PHYSICAL UNIT

2.3.1 RECOMMENDED TOOLS AND SUPPLIES

• Electric drill for mounting holes

• Hammer and center punch

• Tie-wraps

• Drills and circle cutters as needed according the size of screws (or nuts and bolts) used.

• In-line “Power meter” capable of measuring forward and reflected power at the operating frequency

of the radio.

2.3.2 PHYSICAL MOUNTING

a) Start by running all the cables (DC power, CAT5 Ethernet and optional PC RS-232 as well as all anten-

nas cabling) prior to mounting the GeminiG3 unit to assure the feasibility of the planned cable routing.

b) Be sure to leave sufficient slack in each cable so the GeminiG3 unit may be removed from the mount-

ing bracket for servicing with the power applied and the antenna attached.

c) GeminiG3 unit is ready for installation.

Cautions:

• When drilling mounting holes, be careful to avoid damaging some vital part of the vehicle

such as fuel tanks, transmission housing etc. Always check how far the mounting screws extend below the mounting surface prior to installation.

• Use of drill bit stops is highly recommended.

• After drilling, remove all metal shavings before installing screws.

• Do not overtighten self-tapping screws.

1. Once you have found a suitable mounting position for GeminiG3 radiomodem, hold the unit and the unat-

tached mounting bracket in the proposed mounting position and check that there is clearance behind the unit for the heatsink, cables, etc. Check that the position provides a large enough flat surface that the bracket will not be distorted when installed.

Exterior Dimensions: 6.3 x 2.5 in. - Slot Dimensions: 1.0 x 0.2 in.

Figure 1 - Mounting plate and slot dimensions

2. Using the installation bracket as a template, mark the four locations for drilling (see Figure 1). Again, en-

sure that drilling at the selected points is safe and will not cause damage.

3. Indent the drilling positions with a center punch. Drill holes sized for the self-tapping screws or for the

nuts, bolts and lock washers used.

Figure 2 - Bracket installation

Caution: Slightly reduce the size of the drilled holes when using self-tapping screws in thin metal.

4. Install the bracket without distorting (see , bolts and lock washers used.

5. Figure 2 - Bracket installation

6. Securely mount GeminiG3 unit

to the installed bracket using the four supplied metal shoulder screws as shown in Figure 2 above. Push the screws through the rubber grommet and fasten securely to the unit. Do not over tighten.

Figure 3 – Rubber grommet and shoulder screw details

5. Drill any additional holes as required for routing all cables and fit holes with suitable grommets or bush-

ings whenever required.

2.4 ELECTRICAL INSTALLATION

2.4.1 ELECTRICAL REQUIREMENTS

GeminiG3 radiomodem is designed to operate from a 13.8Vdc nominal car battery (negative ground) and requires currents up to 12.0A. It will tolerate a supply voltage range of 10.9 volts to 16.3 volts.

In vehicles with a 24 VDC electrical system (mostly in trucks), it is essential to provide a suitably rated 24/12 VDC converter to isolate the unit from the battery and protect it against excessive voltage.

Warnings:

Always disconnect GeminiG3 radiomodem’s DC power lead before connecting a second battery, using power from another vehicle or power boosting (e.g. when “jump starting” the vehicle).

2.4.2 ROUTING OF POWER CABLE

1. Start by disconnecting the vehicle’s battery unless specifically prohibited from doing so by the customer,

vehicle manufacturer, agent or supplier.

Note: In this event, exercise extreme caution throughout the installation and fit the fuse only when the installation is complete.

The 22 feet (6.7 meters) long power cable consists of three wires attached to a Packard Electric “Weather-Pack” connector (DC power

Connector, see

2. Figure 4).

Figure 4 - DC Power Connector

The DC Power connector has:

• At position “A”, the smaller red switch-sense wire (commonly to ignition)

• At position “B”, the blue ground wire

• At position “C”, a larger red B+ DC power wire (MUST be unswitched)

3. Place this connector at GeminiG3 unit’s radio power input location. Do not connect at this time. See para-

graph 2.6, “Completing the physical installation”.

4. Carefully route both the B and the C wires to where the in-line fuse holder will be installed, usually as

close to the vehicle’s battery as practicable. Ensure that leads do not chafe on any metal part(s). Secure the wires at several locations along their length.

Caution:

Use proper crimping tool. Common pliers are NOT acceptable.

Warning:

The DC Power lead must be unswitched

5. Insert the negative (blue) lead into one of the appropriate connector lug and crimp solidly to force the

metal contacts onto the wires.

6. Repeat the step above for connecting the red DC power lead.

7. Attach the positive lead at the battery positive terminal. Attach the negative wire at the vehicle end of the

battery ground cable.

If the negative cable is connected directly to the battery negative terminal, it

should be fused in case of failure of the vehicle’s ground cable.

Ensure tight and secure connections.

8. Fasten the fuse holder and leads.

9. Carefully route the “A” wire to where the connection will be made for switch sensing.

• Connect to “Ignition” if you wish to have GeminiG3 unit turning ON and OFF dependent on the vehi-

cle’s ignition key.

• Connect to “Accessory” if you wish GeminiG3 unit to be available when the engine is not running, but

still dependent on the ignition key.

• Connect to a user-supplied control switch.

• In installations equipped with a “ChargeGuard”, connect to the controlled-side of the ChargeGuard

(remembering that the DC Power lead must NOT be switched).

10. Make appropriate connections.

Cautions:

Where scraping to bare metal was required, and at the battery posts where wire ends and lugs may be exposed, apply anti-corrosion compound.

Insert the fuse only when installation is complete and ready to test.

11. At the GeminiG3 radiomodem’s position, neatly coil cable slack and attach securely.

2.5 ANTENNA

The main transmitter antenna must be vehicle-mounted to provide a separation distance of 50 cm or more from all persons and the antenna gain must not exceed 5dBi (with a 1.6dB cable loss).

2.5.1 RECOMMENDED TOOLS AND SUPPLIES

• Circle cutter, hole saw or socket punch for antenna

• Appropriate crimping tool for type of connection present on the radiomodem unit

2.5.2 PLANNING

19.7in.

≥24in.

Referring to Figure 5, the GeminiG3 radiomodem commonly uses three separate antennas:

• “T” - Main transceiver -

Constraints are the limit of 50 cm (see section 2.5 above) and omni-directional factors

• “R” - Auxiliary receiver –

Constraints are the receiver spacing of at least 5/8 λ (wavelength) from transceiver antenna and omni- directional requirements

• “G” - Global Positioning System (GPS)

Constraints are TX spacing of at least 24-in/60.96 cm from all transmitting antennas and a clear view of the sky.

.3cm

Figure 5 - Antenna spacing

For the optimum antenna spacing at the frequency you are using, consult System Engineering.

For installation of ground-plane dependent antennas, the center of the metal surface used for mounting is preferable for best omni-directional pattern. For ground-plane independent antennas, installation may be close to the edges of the surface.

Install the antennas in one of the following positions:

• Most preferred for all antennas: centerline of roof. For transmitter antenna, it is the ONLY acceptable po-

sition.

• Less preferred for receiver antenna: trunk lid, providing distance to transmitting antenna is respected

whether lid is opened or closed.

• Much less preferred, but permissible for receiver antenna: left or right rear fenders, just in back of rear

window

• Least preferred, but permissible for receiver antenna: left or right front fenders, ahead of windshield

Proximity to other vehicle-mounted antennas may cause mutual interference especially at higher frequencies.

2.5.3 ANTENNA INSTALLATION

1. Route good quality 50-ohm coaxial cables (e.g. RG-223) from each of the selected antenna positions to

the position where the GeminiG3 unit is mounted.

2. Terminate the end at each of the antenna positions with the appropriate connector for the antenna used

and make the connection.

3. At the GeminiG3 unit position, cut the three cables to length and terminate with the appropriate plug. For

the transceiver and the auxiliary cables, use the proper crimp plug for the connections present on the radiomodem. For the GPS

4. Positively identify the transceiver plug and connect to the left rear of GeminiG3 unit.

5. Positively identify the auxiliary receiver plug and connect to the front left of GeminiG3 unit to the RX po-

sition.

, use a SMA connector.

6. Connect the SMA connector to the GPS position below the auxiliary connector position.

7. Do not skip this last step, trust us; it is an important one. To complete the installation, tie-wrap together

the auxiliary and the GPS antenna cables at a point about two inches in front of the unit. It will be much easier hereafter to correctly identify which plug goes where. You DO NOT want to cross the auxiliary plug with the transceiver plug.

2.6 COMPLETING THE PHYSICAL INSTALLATION

To complete the physical installation and prior to testing the GeminiG3 radiomodem:

• Connect DC Power cable’s connector to the GeminiG3 unit connector until you hear a click as the two

parts snap together.

• Re-check that all other connections are secure (antennas, PC, etc.)

• Switch vehicle ignition ON.

You are now ready to check for normal operation and to run the GeminiG3 Web Interface program for testing or trouble-shooting

2.7 CHECKING OUT NORMAL OPERATION

Check that the vehicle ignition is ON.

1. Check for proper operation of the GeminiG3 LEDs as per Table 2 on page 20.

If checked, the channel is accessible when the mobile needs to roam to a new base station.

There may also be an icon appearing next to the checkbox to indicate if the channel is currently in use or is a preferred neighboring channel:

Channel currently in use Preferred neighboring channel

This informat ion is provided by the base broadcasting its own frequencies and those of its neighboring channels. If the associated frequencies match, an icon will appear next to the Enable checkbox.

On subsequent roaming, the preferred channels will be scanned first.

Enter RX and TX frequency in MHz in the appropriate dialog box. Entries must fall within the Min and Max indicated on top of the page and must be multiples of corresponding frequency step (6.25 KHz for 700/800 MHz frequency ranges or 5, 6.25, or 10 KHz for UHF frequency ranges).

CalAmp recommends (in North America) offsetting the TX column frequency by +30 MHz for 700MHz frequency ranges, by –45 MHz for 800 MHz frequency ranges, or by ± 5 MHz for UHF frequency ranges.

E.g.: Assuming: Min Rx=851.000 000 MHz

Max Rx=869.000 000 MHz Offset=-45.000 000 Mhz

If selection for a channel's RX was: Rx (MHz)=853.037 500 then its corresponding TX would be computed as: Tx (MHz)=853.037 500+(-45.000 000)=808.037 500

4.7.3.6 NAT OVERVIEW

The purpose of the “Network Address Translation” (NAT) protocol is to hide a private IP network from a public network. The mechanism serves both as a firewall function and to save IP address space.

Figure 22 - Basic NAT Operations

The source address of packets transiting from the private network to the public network gets translated by the NAT enabled device. The original IP source address gets replaced by the NAT enabled device’s own IP address (address of the outgoing interface). The NAT module creates an address translation table that is used when traffic is coming back from the public network to the private network.

In our example, Host 1 sends a packet to Host 2. The Host 2 device doesn’t see the private IP address of Host

1. When Host 2 sends a reply to Host 1, Host 2 uses the destination IP address 192.168.1.1, this gets translated back to the appropriate destination IP address by the NAT enabled device.

NAT does a lot more than simple translation of the IP source address. NAT also carries out IP protocol dependant translation. For UDP and TCP protocols, NAT will also translate the source port numbers. Special handling is also done for other more specific protocols like FTP.

4.7.3.7 SNMP OVERVIEW

SNMP (Simple Network Management Protocol) is used by network management systems to manage and monitor network-attached devices. SNMP is based on the manager/agent model consisting of a manager, an agent, a database of management information, managed objects, and the network protocol. The manager provides the interface between the human network manager and the management system. The agent provides the interface between the manager and the physical devices being managed (Figure 28). SNMP uses basic messages (such as GET, GET-NEXT, SET, and TRAP) to communicate between the manager and the agent.

Figure 28 - SNMP: manager/agent model

MIB

The manager and agent use a Management Information Base (MIB), a logical, hierarchically organized database of network management information. MIB comprises a complete collection of objects used to manage entities in a network. A long numeric tag or object identifier (OID) is used to distinguish each variable uniquely in the MIB and SNMP messages.

GEMINIG3 MIB FILE

Each GeminiG3 unit firmware package is bundled with three MIB files (found inside mibs.zip file):

• dataradio-regs.mib: contains a top level set of managed object definitions aimed at managing CalAmp prod-

ucts.

• 1213.mib: contains a set of managed object definitions aimed at managing TCP/IP-based internets.

• gcu3.mib: contains a set of managed object definitions aimed at managing CalAmp mobile units.

OID

In SNMP, each object has a unique OID consisting of numbers separated by decimal points. These object identifiers naturally form a tree. Figure 29 illustrates this tree-like structure for 1213.mib, which comes bundled with every ParagonP4 unit package. A path to any object can be easily traced starting from the root (top of the tree).

ample, object titled “SNMP” has a unique OID: 1.3.6.1.2.1.11. The MIB associates each OID with a label (e.g. “SNMP”) and various other parameters. When an SNMP manager wants to obtain information on an object, it will assemble a specific message (e.g. GET packet) that includes the OID of the object of interest. If the OID is found, a response packet is assembled and sent back. If the OID is not found, a special error response is sent that identifies the unmanaged object.

Figure 29 - Branch of the 1234.mib OID tree

VIEWING MIB FILES

To view the hierarchy of SNMP MIB variables in the form of a tree and view additional information about each node, CalAmp recommends opening all MIB files with a MIB browser. In a MIB browser, each object (or node) can be selected and its properties (including its OID) can be observed. For simple networks, a basic, free application such as ”iReasoning MIB browser” could be used.

However, for managing complex networks, CalAmp recommends a more advanced software application, one capable of browser function as well as being a full-featured SNMP manager, such as the optional “Castle Rock SNMPc Network Manager”. Refer to Network Management using SNMP User Manual (Part no. 120 47001-nnn for more details).

These eight branches expand into additional branches and leaves. Again, all gcu3.mib objects can be accessed through a MIB browser.

Figure 30 – gcu3.mib Tree

Note: Although each mobile is equipped with an SNMP agent, frequently requesting statistics and diagnostics from the mobiles can create traffic jams.

It is strongly recommended to access mobiles’ diagnostics and statistics through the Mobile Tables on the base stations and to only use gcu3.mib for trap reporting.

Multicast White List

passed to the "LAN". When "Multicast Forwarding" mode is enabled and some multicast groups are specified in the "Multicast White List", only the multicast packets identified in the list are passed to the "LAN".

4.7.3.8.1 IP BROADCAST/MULTICAST OVERVIEW

When an IP packet needs to reach more than one unit, the destination address can be set to either a broadcast address or a multicast address.

Figure 32 - Broadcast Window Detail

4.7.3.8.2 BROADCASTS

There are two types of IP broadcast addresses:

• Directed broadcast

A directed broadcast address is an IP address where the host portion is all ones (for instance

172.30.1.255 is the directed broadcast address for the network 172.30.1.0/24, 172.30.1.207 is the directed broadcast address for the network 172.30.1.192/28).

• Limited broadcast

The limited broadcast address is 255.255.255.255.

Note:

Routing equipment (to prevent broadcast storms) do not by default forward limited broadcast packets (255.255.255.255). On the other hand, directed broadcast packets are by default forwarded because these packets are routable like any other unicast packets.

4.7.3.8.2.1 DIRECTED BROADCAST

Each interface of a unit has its own IP address and netmask. From the IP address and netmask, it is easy to calculate the broadcast address associated to the interface. For instance, if the Ethernet interface address of a GeminiG3 radiomodem is 172.30.1.1/24 and the RF interface address is 10.0.1.2/24, then the broadcast address of the Ethernet interface is 172.30.1.255 and the broadcast address of the RF interface is 10.0.1.255.

The “Directed Broadcast” option buttons let the user select whether the unit must forward (or not) directed broadcast packets. Upon reception of a directed broadcast packet, the unit takes the following actions:

If the directed broadcast address matches with one of the unit’s interface broadcast addresses:

• Keep a copy for itself (pass to internal applications, if any).

• If directed broadcast packets can be forwarded (Directed Broadcast is enabled):

Forwards the packet according to the routing table.

• If directed broadcast packets cannot be forwarded (Directed Broadcast is disabled):

Silently discards the packet.

Note:

Occasionally, the unit cannot determine that the packet is actually a directed broadcast. In such a case, the packet is normally routed.

EXAMPLE (DIRECTED BROADCAST FORWARDING ENABLED)

Figure 33 - Example of Directed broadcast forwarding enabled

In this example Figure 33, directed broadcast forwarding is enabled on the Base unit and on Mobile (1) unit. If Sender wants to reach Mobile Host (1), Mobile Host (2) and Mobile Host (3) with a single packet, he can send

to destination address 172.30.1.255.

EXAMPLE (DIRECTED BROADCAST FORWARDING DISABLED)

Figure 34 - Example of Directed broadcast forwarding disabled

In this example Figure 34, directed broadcast forwarding is enabled on the Base unit and disabled on the Mobile (1) unit. If Sender sends a packet to destination address 172.30.1.255, the packet would be discarded by Mobile (1), it would not reach Mobile Host (1), Mobile Host (2) and Mobile Host (3).

If the user wants the Base unit to do the discarding of the directed broadcast packets, then the directed broadcast forwarding must be disabled on the Base unit itself.

4.7.3.8.2.2 LIMITED BROADCAST

The “Limited Broadcast” enabled/disabled option buttons control limited broadcast packets forwarding. When enabled, the unit forwards limited broadcast packets.

Upon reception of a limited broadcast packet, the unit takes the following actions:

• Keeps a copy for itself (passes to internal applications, if any).

• If limited broadcast packets can be forwarded (Limited Broadcast is enabled):

• If limited broadcast packets cannot be forwarded (Limited Broadcast is disabled):

Silently discards the packet.

EXAMPLE (LIMITED BROADCAST FORWARDING ENABLED)

Figure 35 - Example of Directed broadcast forwarding enabled

In this example Figure 35, limited broadcast forwarding is enabled on the Base unit and on all Mobile units. If Sender wants to reach Mobile Host (1), Mobile Host (2) and Mobile Host (3) and Mobile Host (4) with a single

packet, he can send to destination address 255.255.255.255.

Notice that Sender and Base units are on the same LAN (routing equipment does not usually forward limited broadcast packets).

In this example Figure 36, limited broadcast forwarding is enabled on the Base unit, disabled on the Mobile (1) unit and enabled on the Mobile (2) unit. If Sender sends a packet to destination address 255.255.255.255, the packet would reach Mobile Host (4) only. The Mobile (1) unit would discard any limited broadcast packet it received from the Base unit.

If the user wants the Base unit to do the discarding of the limited broadcasting packets, then the limited broadcast forwarding must be disabled on the Base unit itself. Then no Mobile Host unit would ever be receiving a limited broadcast packet.

4.7.3.9 MULTICAST

IP multicast addresses are in the range 224.0.0.0 to 239.255.255.255. These addresses are used to represent logical groups of units that may or may not reside on the same networks.

Multicast is used when “one-to-many” communication is required. For instance, a radio station might offer a music channel on the Internet in real time. To receive the music a receiver-host must know the multicast group (multicast address) used by the radio station sender-host and add itself as a member of this group. In the IP realm, a host uses the IGMP protocol to do this. The routers inside the Internet are using IGMP and other multicast routing protocols to build the proper path from the sender to the receivers (a tree-like path is

formed from the sender to the receivers).

Figure 38 - Reception of multicast packets (Second step)

In the E-DBA environment, an outside sender-host might be interested in sending multicast packets to any one of the following groups:

• “All Base” group (not currently supported)

• “All Mobile” group (DMP-IP only)

• Various “Mobile Host” groups.

The Base (P4 in the illustration) units are directly connected to the outside network. ALL multicast groups MUST be identified in the Base because the Base unit uses IGMP to register the memberships to the multicast groups on behalf of the other units (Mobile units, Mobile Host units).

4.7.3.11 SETUP (ADVANCED) ► TIME SOURCE

To facilitate tracking of events in a network, the Paragon4 base station and the GeminiG3 radiomodem can initialize their real-time clocks using a number of protocols. At reset time, the Paragon4 base station can use the SNTP protocol (RFC2030) to pick up the current UTC (Universal) time. Setting the “TimeZone” and “Daylight Savings” options allows displaying the correct local time in the “Unit Status” web page.

Description

4.7.4.3 GPS ►AAVL

The “Autonomous Automatic Vehicle Location” (AAVL) feature adds the ability for GPS-equipped GeminiG3 models to initiate "Here I am" position message transmissions. AAVL allows the system designer to specify the maximum distance or the time interval between position reports:

 If the vehicle moves more than a specified distance since its last report, a new position report will be gen-

erated.

 If no report has been sent for a specified amount of time, a new position report will be generated.  AAVL inhibits excessive transmission of reports to prevent network overload.

The “Dynamic Bandwidth Allocation” (DBA) protocol’s “Out Of Band” (OOB) mechanism is used to deliver these “Automatic Vehicle Location” (AVL) reports.

Figure 47 - GPS - AAVL

Report every (*2) meters

Report every (*10) seconds

At least (*10) seconds between reports

MDBR – (Maximum Distance Between Reports) Distance interval - the vehicle sends a position update each time it has moved this dis-

tance (unless the minimum time interval has not yet elapsed). The mobile firmware saves the last-transmitted position, and compares it with the current

(latest OOB update) position. This parameter controls the “Maximum Time interval between position Reports”. Thus,

the vehicle will send a position update every time “this interval has elapsed” guaranteeing delivery of position reports at least this often. Data traffic and ACKs will generate additional reports at shorter intervals.

At most, the vehicle sends a position update every time this interval, in seconds, has elapsed.

The main purpose of this parameter is to protect the network from being overloaded by excessive AVL reporting from one or a few mobiles.

5.3.2 GPS TEST

About three minutes after ignition is turned-on, the PWR LED on the GeminiG3 unit front panel should flash in blink- ing amber on green color at the rate of one pulse per second (1pps). This indicates that the GPS has acquired the sky

position of a sufficient number of satellites to arrive at a ground position solution.

If the GPS has a good view of the sky and still has not generated any position solution within three minutes (it may take up to 10 minutes or more if the sky view is partially blocked.), the following trouble-shooting procedures should be undertaken to isolate the fault:

1) Disconnect the GPS antenna cable connector from the Gemini radio and check for + 5 VDC on the center pin of the GPS antenna connector on the radio using a Digital voltmeter (DVM). If the voltage is present, do not reconnect the cable and proceed to step 2.

2) With the DVM, measure resistance between the shell and the center conductor of the GPS cable, resistance should be between 100 and 300 Ohms, if it measures open or short circuit the GPS antenna is either a passive antenna which is the WRONG type, or a defective active antenna, replace with a known good active antenna.

3) Connect the new antenna to Gemini and wait about three minutes for the “PWR/PGM LED to start flashing at a rate of 1 pulse per second (amber on green) on the GeminiG3 unit indicating that a position is acquired. If no position acquisition occurs, the modem and/or its GPS receiver may be defective.

The User’s Interface GPS Web Pages are located starting at paragraph 4.7.4.

5.4 TROUBLESHOOTING TOOLS

5.4.1 NETWORK CONNECTIVITY

• PING (DOS/WINDOWS)

The ping command determines whether a specific IP address is accessible. It works by sending a packet to the specified address and waiting for a reply. It is useful for troubleshooting “end-to-end” reachability, network connectivity, and network latency.

Available for MS-Windows 9x, ME, NT, 2000, XP, and Win7 as well as Unix & Free BSD.

EXAMPLE:

ping 192.168.204.1 displays the response with turn around time in milliseconds.

• TRACERT (WINDOWS)

The tracert command is used to visually see a network packet being sent and received and the number of hops required for that packet to get to its destination.

Available for MS-DOS 6.2, MS-Windows 9x, ME, NT, 2000, XP, and Win7.

Note:

Users with MS-Windows 2000 or XP who need additional information on network latency and network loss may also use the pathping command.

EXAMPLE

tracert www.yahoo.com at the command prompt displays the intermediate routers between local host to the www.yahoo.com site.

5.4.2 CONFIGURATION INFORMATION

• WINIPCFG (WIN95/98), IPCONFIG (WIN2K) or IFCONFIG (UNIX)

Ipconfig is a DOS utility, which can be used from MS-DOS or a MS-DOS shell to display the network settings currently assigned and given by a network. This command can be utilized to verify a network connection as well as to verify network settings.

Available for MS-DOS, MS-Windows 9x, ME, NT, 2000, XP, and Win7.

EXAMPLE

ipconfig /all at the command prompt displays the Ethernet MAC address, IP address, IP netmask, default IP gateway, DNS server… information.

• ARP

View and update the system ARP table

• ROUTE

The Address Resolution Protocol (ARP) is used with the IP protocol for mapping a 32-bit Internet Protocol address to a MAC address that is recognized in the local network specified in RFC 826. Once recognized the server or networking device returns a response containing the required address.

Available for MS-Windows 9x, ME, NT, 2000, XP, and Win7.

EXAMPLE

arp -a displays all entries in the ARP cache. Useful in manipulating ARP caches.

View and update the system routing table

The function and syntax of the Windows ROUTE command is similar to the UNIX or Linux route command. Use the command to manually configure the routes in the routing table.

Available for MS-Windows 9x, ME, NT, 2000, XP, and Win7.

EXAMPLE

route ? displays help

route print displays the routing table

5.4.3 STATISTICS INFORMATION

5.5 FIRMWARE UPGRADING

The GeminiG3 radiomodem firmware is field-upgradable using the unit’s Ethernet port. The process involves connecting to the IP address of the mobile from a host PC and transferring the firmware files via an FTP program.

5.5.1 PROCEDURE

1. Using a file decompression program, such as WinZIP™ or WinXP’s right-click & select the “Expand to…” (or

“Extract to…”) option, expand the contents of the firmware upgrade package to a directory of your choice on the host PC.

Warning:

Be aware that base and mobile’s firmware archives are often distributed at the same time. Files intended for the GeminiG3 radiomodem are labeled in the form GeminiG3_edba_Vx.x_Rx.xx.zip. Be careful not to transfer firmware into the wrong unit!

2. Using an FTP program of your choice, establish a connection to the mobile IP address. Please refer to para-

graph 4.7.5.1 for “Username” and “Password” usage.

3. Transfer all the files in the upgrade package. Occasionally, long pauses, on the order of 30 to 45 seconds, are

possible when storing the file in the unit’s flash file system.

4. Once the file transfer is complete, cycle the mobile power and allow the unit to boot. The unit should return to

the state that it was in when the update was started.

Note:

After resetting, the PWR LED remaining lit steady amber or red indicates the FTP transfer was not successful or that the firmware is corrupt. Please contact CalAmp system engineering for assistance.

5. Verify the integrity of the newly transferred files.

a) Connect to the mobile’s IP address using an Internet browser such as IE (5.0 or later) or Mozilla. b) Enter the user name and password (in the usual manner) and allow the Welcome page to load. c) In the left pane, click on Unit Status. The Unit Identification and Status pane should display the newly

upgraded firmware in its Banner (should correspond to the upgrade package version) and the H/W Status should also show Ok.

d) In the left pane, click on Maintenance, then on Package Control. Wait a few moments for the results to

display. Figure 52 shows a “Pass” result indication.

Figure 56 - Sample FTP program

5.5.1.1 FILE INTEGRITY FAILURE
